I came from the Evo 4G. Didn't get 4G but do get LTE on the Rezound. If you can get a stable 4G connection, I'd have to say the video is slightly better on the Rezound. The HD channels are great. On WiFi, the Rezound is also a bit better. But your Sling stream is still limited by your network's upload speed which for some can be the narrowest path in the stream.
